为onClickListner()
和PositiveButton
实施NegativeButton
builder.setNegativeButton("Close", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int whichButton) {
// what ever you want to do with No option.
builder.dismiss();
}
});
和
builder.setPositiveButton("Help Translate", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int whichButton) {
builder.dismiss();
Intent browserIntent = new Intent(Intent.ACTION_VIEW, Uri.parse("http://www.example.com"));
startActivity(browserIntent);
}
});

你可以使用getButton(BUTTON_POSITIVE)获取Button;
http://developer.android.com/reference/android/app/AlertDialog.html#getButton(int)
然后,当您单击“帮助翻译”按钮时,您可以执行类似的操作:
Intent browserIntent = new Intent(Intent.ACTION_VIEW, Uri.parse("http://www.google.com"));
startActivity(browserIntent);
